So there have been tons of post about this head unit lately and a lot of good things about it. I just want to put this out. The fact that it does not have front rear and sub pro outs SUCKS!!! I purchased it assuming there were sub out puts and well.... So what I did right now. I put a Y splitter on it so its like I have 4 front speakers all around and it sucks when the gps comes through. So I think what I am going to do now is get an active EQ with sub out put. I was wondering if anyone has done this or has any better ideas. I need to run this head unit with the pre outs going to my amp. My 4 channel does have a pre out for my mono channel amp but gives me no control over the amp. So I figured the EQ would fix all my issues. any more advice??
